Howlite and Phosgenite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Howlite and Phosgenite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Howlite and Phosgenite Optical Properties during the identification of gemstone. Specific gravity of Howlite is 6.13 whereas that of Phosgenite is 6.13.
